Beyer Gambit C20 Center Game
Center Game: Beyer Gambit
Black copies White's d4. Although this approach of pushing ...d5 can be plausible against the King's Gambit (in the Falkbeer Countergambit), here it is simply unfavorable for Black. With good play, White can gain a good and superior position.
The Beyer Gambit can be met with two responses. 3. exd5?! is not bad, but gives away White's advantage. After 3...Qxd5, Black's position is quite playable with no big problems and no material deficit.
3. dxe5 is testing of the Beyer Gambit. White captures the free black pawn on e5. if Black copies with 3...dxe4, 4. Qxd8+! Kxd8 leaves White with a very favorable endgame where the black king cannot castle and is on the open d-file. Black can play a gambit with 3...d4, but it will be hard for Black to prove compensation for the lost pawn.
3. f4!? transposes to the Hinrichsen Gambit of the Falkbeer Countergambit.
